Hello
I am new to this and glad that I can get help here, my problem is this :

I have Make a river table using glasscast 50, sanded it down then layed a lay of glasscast 3 coat (3mm = 1kg/m2) I heated the surface gently to remove the bubbles using a hot air blower, this worked fine, I could se more small bubbles continuing to come but they bubbles away by the next day (most of them but not all) but I can see the surface is not perfectly smooth there are a lot of small indentations in he surface a bit like an orange peal effect. The room was heated to around 18 degrees.

I am thinking of sanding down the the surface once its dry (after 72 hours) to remove any surface bubbles and give a key for the next layer, warm the resin to reduce its viscosity allowing it to run out better , heat the room up to 25 degrees, pour another 3mm layer and then hope. 

Any thoughts ????

Thanks David
